Altronix MAXIMAL75 Access Power Controller w/ Power Supply/Chargers, 16 Fused Relay Outputs
- 115VAC 60Hz, 7.0 amp input
- 12VDC and 24VDC outputs
- Sixteen (16) auxiliary power outputs (unswitched) (outputs are rated 2.5 amp)
- Filtered and electronically regulated outputs (built-in power supply)
- Thermal and short circuit protection with auto reset

Maximal 75 distributes and switches power to access control systems and accessories. It converts a 115VAC 60Hz input into sixteen (16) independently controlled 12VDC and 24VDC fuse protected outputs. These Fail-Safe/Fail-Secure power outputs may be converted to dry form "C" contacts. The outputs are activated by an open collector sink or normally open (NO) dry trigger input from an Access Control System, Keypad, Push Button, REX PIR, etc. Units will route power to a variety of access control hardware devices including: Mag Locks, Electric Strikes, Magnetic Door Holders, etc. The FACP Interface enables Emergency Egress, Alarm Monitoring, or may be used to trigger other auxiliary devices. The fire alarm disconnect feature is individually selectable for any or all of the sixteen (16) outputs.
